Abstract -------------------------------------------------------- This CK contains sample CASSINI spacecraft orientation. This file was generated by running prediCkt program with the set of setups provided in the sections below. CASSINI SPICE Kernels Used in the prediCkt Run Generated This File -------------------------------------------------------- The kernels provided in support of the construction of the attitude given in this kernel are listed in the small comment block preceding this description. The SPK kernel providing the spacecraft trajectory (140114AP_SK_13290_17265.bsp) was suggested by Julie Bellerose, JPL on December 29, 2014. Note that since this CK contains predicted data it must be used with the SCLK kernel with which it was generated. Orientation Mode Definition -------------------------------------------------------- This section defines CASSINI s/c orientation mode simulated in this file. The "PXNSPPYSUN" mode is based on the following description provided by Susan Linick, JPL in the e-mail from January 7, 2015 with the subject "Re: Request for quick turnaround of C-Kernel data": Primary Axis: +X to NSP Secondary Axis: +Y to Sun The following keywords define the this attitude: \begindata DIRECTION_SPECS += ( 'ToSun = POSITION OF SUN -' ) DIRECTION_SPECS += ( 'FROM CASSINI -' ) DIRECTION_SPECS += ( 'CORRECTION LT+S' ) DIRECTION_SPECS += ( 'SaturnNorth = FIXED IAU_SATURN -' ) DIRECTION_SPECS += ( 'XYZ 0 0 1' ) ORIENTATION_NAME += 'PXNSPPYSUN' PRIMARY += '+X = SaturnNorth' SECONDARY += '+Y = ToSun' BASE_FRAME += 'J2000' \begintext Orientation Schedule -------------------------------------------------------- This section defines the CASSINI orientation schedule implemented by this CK file. The schedule below was provided by Susan Linick, JPL in the e-mail from January 7, 2015 with the subject "RE: Request for quick turnaround of C-Kernel data": Rev 281 Start time: 24-JUN-2017 22:16:07.5157 UTC End time: 04-JUL-2017 22:16:07.5160 UTC In the keyword assignments below the times are given as ETs: \begindata CK-SCLK = 82 CK-SPK = -82 CK-FRAMES = -82000 CK-82000ORIENTATION += 'GOTO PXNSPPYSUN' CK-82000START += @2017-06-24-22:17:14.700 CK-82000STOP += @2017-07-04-22:17:14.700 \begintext End of prediCkt setup.
